Product Description:

Green Silicon Carbide




Green Silicon Carbide is an extremely hard (Knoop 2600 or Mohs 9.4) man made mineral that possesses high thermal conductivity (100 W/m-K). It also has high strength at elevated temperatures (at 1000°C, Green SiC is 7.5 times stronger than Al2O3). Green SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2815.5°C.


Green SiC is an entirely new batch composition made from Silica sand and coke, and is extremely pure. It can be manufactured in many complex bonded shapes, which are utilized for superrefractory purposes. Green SiC is also ideal for a wide variety of abrasive applications.

Q:What kind of refractory decorative board has good quality?
Baby Rabbit has excellent refractory decorative board. It once won the Chinese famous brand, and was awarded iconic brand in plywood industry and the most influential integrated service providers of indoor decoration materials . Fireproof panel is made from body paper(titanium coated paper, kraft paper) in high temperature and pressure through impregnation technology of melamine and phenolic resin. Refractory door slab is made by sticking fireproof panel on base materials such as density board or chipboard.
Q:Are the specification of fireclay bricks and ordinary clay brick the same?
Do you want to know whether the specifications of fireclay bricks and ordinary clay brick are the same?
Q:what's the seal of fireproofing material?
Organic fire-proof caulking is made by taking organic synthetic resin as bond and compressing the components together after adding fireproofing agent, filler. The putty won't solidify after a long time usage and has good plasticity, can be sealed arbitrarily. This kind of putty is mainly applied in opening's fireproofing and sealing project of construction pipe and electric wire and cable, and it's used with ATD-AB and fire retardant bag together. ATD-AB is a kind of gray powder material, after mixed with water, it can be used for the opening sealing of electric wire and cable or fire resisting wall of wire tunnel. The fire proof blockage is non-toxic, and no smell, has good water resistance and oil resistance with simple construction methods. It's oxygen index is 100 and it belongs to incombustible material. it's refractory time can reach 3 hours, or above or below. as for some projects for perpetual usage, WXY-II will save the project fee and make the project solid. A kind of fireproofing material that can automatically expand and foam and sealed by opening after injecting the foam into opening. Sealing strip is a product or flexibility coiled material mede by fireproofing material with certain geometry shape. Sealing gum is a kind of liquid fireproofing material that has a function of fireproofing and sealing. Fire retardant bag is soft and windable tape-shaped product made by fireproofing material, it is winded on the external surface of plastic pipe and fixed with steel belt or other proper methods, it's the expansion, squeezing and softening pipe after contacting with fire, opening left by burning or soften of seal plastic pipe. Fire retardant ring
Q:what is the material of fixed first rate fire resistant window?
Fixed first rate fire resistant window is produced by the steel sash windows, steel casement, fireproofing glass. Fireproof windows, is composed by steel window frame, steel casement, fire-proofing glass. it refers to the window which can isolate and stop the fire spreading. The fire window product is named after the main material of window frame and the window casement, window frames is made of steel, casement is made of wood or the sash frame is made of wood and the casement is made of fire window.
Q:How to distinguish the fire rating of rubber and plastic thermal insulation material?
It is divided into level A, B1, B2 and B3. According to the current "burning behavior of building materials classification method", Level A insulation material is a non-combustible material, which belongs to YT. However, from the point of view of the current market , level A insulation material are very few, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the more welcomed by the market is the organic insulation material. This is characterized as thermal insulation material, which is divided into three levels: level B1 is flame retardant, level B2 is flammable and level B3 is flammable. The level B1 nonflammable thermal insulation material is determined according to the fire endurance of the material. And different parts of the material are divided differently! Such as the common EPS / XPS insulation boards through special treatment of adding flame retardant. . Level B2 combustible insulation material is commonly the EPS expanded polystyrene foam insulation board and XPS board, that is, the ordinary plate. This material has low ignition point, and releases large amounts of harmful gases in the combustion process . Level B3 flammable insulation material is commonly the thermal insulation material taking polystyrene foam as the main material. Since this material is highly flammable, it has been out of the external wall thermal insulation materials. As for the civil construction insulation materials, China's current popular building insulation materials in the market are mainly made of three organic foams: EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane).
Q:Using what kind of melting aluminium furnace refractories is more appropriate?
If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.
Q:What material is refractory material?
alumina refractory concrete, silica brick clay brick, metal ceramic, high temperature machine coating fiber reinforced ceramics, diatomite product, asbestos products, insulation board refractory. The definition of refractory can be searched in the website.
Q:What are the requirements for the performance of refractory materials?
Performance requirements for electric furnace lining refractory: 1, sufficient refractoriness and softening point. Because of eletric arc, the inner surface temperature of lining can be as high as 1500 to 1800 degree. 2, strong resistance to slag. Because the dust penetrate into the furnace through pore lining, and the refractory material subject to loss, leading to spalling. 3, good thermal and shock resistance. Because during steelmaking, opening door and lifting of the furnace will lead to sudden changes in the temperature of the furnace lining refractory material, so spalling and cracking may occur, damaging the lining premature. 4, enough strength, because the lining is impact during charging, tilted when vibration,and eroded by metal, slag and airflow. 5, the thermal conductivity shall be small, and the conductivity shall be low. The commonly used furnace refractories are dolomite brick, magnesia brick, high alumina brick, silica brick and magnesia ramming etc.. Because of different working conditions of the various parts of the furnace, the refractory materials are not the same.
Q:What's the fire endurance of fire windows?
That is fire resistance rating, fire-resistant time in the case of fire! It can be basically classified into the following levels and the fire endurance of the fire window is as follows as well: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. This is in accordance with the latest specification of gb16809-2008 fire windows.
Q:How long is the fire endurance of fire resistant rolling shutter door?
According to the new national standards GB_12955-2008 for fire doors from January 1, 2009, fire doors are classified acoording to thermal insulation fireproof door(A),part heat insulation fireproof door(B) and non thermal insulation fireproof door(C), rather than thermal insulation fireproof door. At the same time, the original fire endurances of class A, B and C fire doors are adjusted to 1.5h, 1.0h and 0.5h respectively. So, GB is 1.5h
